--- Comment #4 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- Most configurations (for which the libc used has a working stdint.h) should probably be using use_gcc_stdint=wrap, so that GCC's stdint.h includes libc's for hosted compilations but GCC's own for freestanding compilations. *-*-elf configurations do, for example. I'd advise adding that for nvptx. This test deliberately uses -ffreestanding so that any configurations using GCC's stdint.h for freestanding compilations have no problems with system stdint.h lacking TS 18661-1 support.
